Novel Three-Phase PWM Voltage-Fed Rectifier with an Auxiliary Resonant Commutated Pole Link

Abstract

A novel auxiliary resonant commutated pole (ARCP) link for three-phase PWM voltage-fed converter is presented. The ARCP link consists of two auxiliary switches, one resonant inductance, and six diodes, which is simpler than the conventional ARCP designs. Based on the phase and amplitude control, the proposed converter can take a minimum switching times PWM method, which results in reduced losses and a simplified control. In addition, the zero-voltage resonance modes are analyzed. Finally, simulation and experimental results show that the system can realize zero-voltage switching with a unity power factor.

Rating analysis and comparisons of resonant circuit based sustain drivers for PDPs

“…In particular, the resonant circuit based sustain drivers, converting high dc voltage to ac square-wave voltage with high frequency for strong visible light emission, are regarded as a key part of the overall PDP driving system. Thus, in recent years, industrial and academic researches have introduced numerous sustain drivers to address distinctive characteristics [6][7][8][9][10][11][12][13][19][20][21]. However, most of the presented works have focused on operational modes and their own advantages of the specific structures, without granting relevant comparisons with other structures from standpoint of performance.…”
